Maintaining the engine oil in your 2021–2022 Kia Seltos is crucial for optimal performance and longevity. This compact SUV offers two engine options: the G4FJ 1.6L I-4 petrol engine and the G4NH 2.0L I-4 petrol engine. Both engines require an oil capacity of 4.2 quarts and recommend the use of 5W-30 viscosity oil, ensuring smooth operation under various driving conditions.
In addition to oil maintenance, it's important to monitor coolant levels for each engine. The G4FJ engine has a coolant capacity of 7 quarts, while the G4NH engine requires 5.7 quarts. Regularly checking and maintaining these fluids will help keep your Kia Seltos running efficiently and prevent potential engine issues.
